DS250DF810: link could not establish

2025-04-11 分类：接口/时钟 阅读(131)

Part Number:DS250DF810

dears,

My customer used DS250DF810 between the switch chip CTC7132 and the optical module. The hardware connection block diagram is as below:

The test environment: the optical port is self-looped through the optical fiber. 

The register configuration is as below:

value = 0 = 0x0

the DF810 chip ID is read normally, the value of the 0x78 register is read as 0x20, the value of the 0x27 and 28 registers is read as 0x0, and the switch main chip feedback that the LINK to the optical module  is not establish. the issue occurs after the CTC7132 and retimer are configured.

the customer used DS250DF810 previously and it may work normally. the issue happens after change the switch chip to CTC7132 (there is no any other change). The switching chip has been configured normally.  The customer use the DS250DF810 configuration file of the previous mass-produced project. the register of DF810 is attached below:

if bypass CDR after writing the registers of retimer, the port connected to the 4 optical ports  can be Linked up with CTC7132.

would you please help to guide the customer how to resolve the issue?

thnaks a lot!
